Roms won't Play but can be seen...

Jimsky

First of all hello to everyone :)

NOOB to all this, I have built a couple of Bartops using Raspberry Pi and Retropie together but.. I have fresh install of Retropie Via Pi Baker on SD and All load up great and i have done any updates necessary.

My issue is when I load any roms .nes .zip etc etc they all show up lovely and in the correct emulators, I can even Scrape them and get the info, but when I click to play then screen goes as if its going to play but then just comes straight back!
Are there any permissions or settings i need to do before putting roms on!
I'm loading Via Network on a Mac

I'm not massively techie but willing to try.
Thanks in advance Jim

Also i've done Atari 2600 and Sega and none of those load either, just show up .

https://retropie.org.uk/forum/topic/3/read-this-first - give us some clues about your system.
Can you be more specific about which ROM and Emulator are giving you troubles ? Btw, SEGA is not an emulator, you mean Genesis/Megadrive ?

Jimsky

@mitu thanks for the reply,

yes i meant Genesis/Megadrive, Its a Pi 3 B, with a Aukru 3amp power supply , using a Exceria 32GB SD Card, its a Clean install of Retropie.
And its all of them that show the Roms , Snes , Nes, Atari 2600 7800 but do the same.

Just noticed it says when launching
errors are logged to /dev/shm/runcommand.log

if that means anything???

Ignore that , just read about it der!!

mitu

@jimsky Yes, you can find any errors in that file - use the RunCommand launch menu (https://retropie.org.uk/docs/Runcommand/#runcommand-launch-menu) to enable verbose logging and then use SSH to log in on the PI to look at the contents of the file. You can use the nano text editor to open the file by typing nano /dev/shm/runcommand.log and scroll down until you see something that resembles an error.
Are you sure you got the right ROM ? What's the name of the file and which folder did you copy it to ?

Jimsky

@mitu I looked at the nano log and theres nothing there if i'm doing that right by pressing f4 then running the run command log!

The file is .a26 for Asteroids into A2600 folder to be honest i have read about the bios files for some of the others that are required , but i can't even get Asteroids to work lol.

mitu

@jimsky The file you're looking after is /dev/shm/runcommand.log, which should appear after you're trying to run the game. It should have at least the command used to start the emulator, something similar to

Parameters:
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fceumm/fceumm_libretro.so --config /opt/retropie/configs/nes/retroarch.cfg "/home/pi/RetroPie/roms/nes/Akumajou Densetsu (Japan).zip" --appendconfig /dev/shm/retroarch.cfg

@mitu HI and thank you for your input/help.

Basically I reformatted the SD Card and redownloaded Retropie on to another computer to see if it that did anything? And hey presto clean install and 2 tested roms later it works!!!

Bizarre but thank you
